If you have ever tried to learn the Kalman Filter, you know the feeling. You open a textbook, see a wall of Greek letters, matrices, and probability density functions, and immediately feel the urge to close it.

K = P_pred / (P_pred + R); % Kalman gain
x = x_pred + K * (z(k) - x_pred);
P = (1 - K) * P_pred;
